I removed the back cover from my PRO-164 to have a look. To properly repair the connector if damaged would require lifting or removing that metal RF shield. I would not advise anyone that does not posses good soldering skills to attempt that. It requires a vacuum iron to remove the solder without applying heat too long that would damage the circuit card. With good skill, solder wick may work, but not the best way. With a bright light you may be able to see through that opening on the outer side and see if the center pin is disconnected, but I would think it quite difficult to solder through that opening.
